    Bulldog coupler and electric brakes

    My plan was to fix my surge brakes and replace the hydraulic actuator, but a salesman at a local trailer parts store has really been pushing electric brakes. I've already cut out the old coupler and added a tongue extension, so going this route I could upgrade to a bulldog coupler rather than...

    Mounting location of dual battery switch

    I just ordered and received a Perko dual battery switch, but I was surprised at the large size. From the pictures, I envisioned it being fairly small, but it's pretty massive. I had planned to mount it near the helm (preferably on the instrument panel), but due to the size I'm sure even if I...

    Surge brake actuator replacement

    I bought an older Cobalt (1989 21') last spring from a marina, and the tandem axle trailer they included was one they had been using at the marina for many years. Since brakes were never needed, I suppose when they started having trouble with the actuator they just either disconnected or welded...

    Winterizing Volvo 5.7

    I have an older (1989) Cobalt with an AQ271C VP engine. This is my first winter, and I'm hoping to get it winterized this weekend. I've read through the winterization sticky and quite a few threads, and everyone seems to pretty much agree that draining and optionally filling with antifreeze is...

    Another outdrive oil question

    I know this question has been discussed many times in the forum, but there seems to be some contradictory advice. Some advise to just follow the manufacturers recommendation, and others recommend using the Mercruiser high-performance green oil (to keep water in suspension, etc.). I have a...

    Volvo DP-A bellows and upper unit

    I recently purchased a 1989 Cobalt with a Volvo DP-A outdrive. The marina where I bought it greased the u-joints, replaced the u-joint bellows, and replaced the shift cable. I've only had it out a couple of times, but I noticed a water drip at the raw water intake hose so I decided to replace...

    Cobalt 21BR lift shocks

    I have a 1989 Cobalt 21BR which is in need of a new pair of engine hatch/rear seat lift arms/shocks/props/struts (whatever they're actually called). I've contacted a local dealer, but so far they can't find the specs for them. The brand of mine says Suspa, but the numbers are too faded from...

    Volvo DP-A hydraulics and SeaFoam

    Does anyone have any experience using SeaFoam Trans-tune to clean outdrive hydraulics? It says it's not a stop-leak, but it's supposed to clean hydraulic valves and is compatible with all hydraulic systems. I've recently bought this boat (Cobalt 21 with VP DP-A outdrive) and have only had it...

    Raw water intake hose

    I recently purchased a 1989 Cobalt 21BR with a Volvo Penta AQ271C and a duoprop outdrive (DP-A I believe). I've been going through it trying to determine condition as well as to learn how everything works. We've taken it out a couple of times (less than 30 minutes each time) just to practice...
